8 Claims.

This invention relates to a combination cleaner and guard for electricshavers.

The slotted heads and cutter bars of electric shavers have very delicateblades which are liable to injury and corrosion. thereby quicklydestroying the effectiveness of the shaver.

The principal object of this invention is to proride a guard which willprotect the blades from all mechanical contacts and injuries; which willsimultaneously clean the cutter bar of all adherent foreign matter; andwhich will preserve the blades in oil or similar corrosion preventingfluid.

Another object of the invention is to so construct the guard that thecleaning operation will be a part of the use of the guard so that itwill be impossible to place the guard upon the head withoutsimultaneously cleaning the cutter bar and blades.

Other objects and advantages reside in the detail construction of theinvention, which is designed for simplicity, economy, and eficiency.These will become more apparent from the following description.

In the following detailed description of the invention reference is hadto the accompanying drawing which forms a part hereof. Like numeralsrefer to like parts in all views of the drawing and throughout thedescription.

m In the drawing:

Fig. 1 illustrates a typical electric shaver of the open cutter bartype.

Fig. 2 illustrates the same shaver with the improved guard in placethereon.

M Fig. 3 is a perspective view of the guard.

Fig. 4 is a longitudinal section therethrough.

Fig. 5 is a longitudinal section through the head of the shaver with theguard in place thereon.

Fig. 6 is a cross section through the shaver head and guard taken on theline B-6, Fig. 2.

A typical electric shaver is illustrated at II] with its slotted head atl I. In the type of shaver for which this invention is particularlydesigned, the head H is hollow and encloses a reciprocating cutter bar2| having passage I2 throughout its entire length. The head projectsfrom the shaver proper, there being a shoulder [3 formed by the shaverhousing along each side of the head.

The improved guard consists of a channel-like housing or cap M openalong one of its sides. Flanges I5 preferably extend along each edge ofthe open side. One end of the cap I4 is closed by means of an end platel6, which projects beyond the open side thereof, the other end is open.

A brush member ll, preferably of the spiral bristle type formed on atwisted wire stem I8, is soldered or otherwise secured to the end platel6 so that it will project into the channel of the cap it and extendthroughout the length thereof.

It is preferred to allow the free extremity of the 5 brush to projectslightly beyond the open end of the'cap.

The "bottom of the channel contains a leather or felt pad 2B which issaturated with a lubricating and corrosion preventing oil. In theparticular embodiment illustrated, the pad is secured in place by beingpassed through openings in the cap and thence clamped by means of aclamping bale E9. The method of securing the pad is simply illustrativeas it could be secured in place in 5 a variety of ways.

To place the guard on the shaver, it is only necessary to enter theextremity of the brush in the open end of the cutter bar channel I2 andthen push the guard over the head to the position of Fig. 2, with theend plate over-lapping the side of the shaver housing. This forces thebrush il entirely through the cutter bar causing the brush to sweep andclean the entire channel therein. The lubricating pad 20 coats the headand cutter bar with a film of protecting oil and also acts as a cushionto protect the blade edges from contact with the guard.

In this device the brush serves a double purpose, it is not only acleaner for the shaver head but it provides means to hold the guardmember in place without the use of snaps. latches, catches, etc. Thebrush is compressed as it passes into the restricted channel of thecutter bar and the resilient bristles snap along the teeth or bladesthereof to efficiently clean them. The expansion of the brush within thechannel effectively locks the cap thereon until it is manually removed.

While a specific form of the improvement has been described andillustrated herein, it is desired 40 to be understood that the same maybe varied, within the scope of the appended claims, without departingfrom the spirit of the invention.

Having thus described the invention, what is claimed and desired securedby Letters Patent is:

1. A guard member for electric shavers comprising: a channel-likehousing; a stationary brush supporting member aflixed to one extremityof and extending through-out the length of said housing; and bristlesprojecting outward from said brush supporting member toward the innerface of said housing.

2. A guard member for electric shavers comprising: a channel-likehousing having an open side; an end plate closingone end of saidhousing; 56

a stationary brush supporting stem fixed to said end plate and extendingfrom said end plate longitudinally of said housing; and bristlesprojecting radially outward from said stem toward the inner face of saidhousing.

3. A guard member for electric shavers comprising: a channel-likehousing'having an open side; an end plate closing one end of saidhousing; and a spiral bristlebrush member fixed to said end plate andextending from said end plate longitudinally of said housing; and edgeflanges extending along each edge of the open side of said housing.

4. A guard member for electric shavers comprising: a channel-likehousing; a brush member extending throughout the length of said housing;and a pad member secured along the bottom of said housing.

5. A guard member for electric shavers comprising: a channel-likehousing; a brush member extending through-out the length of saidhousing; a pad member secured along the bottom of said housing; andmeans for detachably securing said pad member in place.

6. A guard member for electric shavers comprising: a channel-likehousing; a brush member extending throughout the length of said housing;and a pad member secured along the bottom of said housing, said padmember being saturated with oil. I

7. A combined protecting cap and brush for electric shavers of the typehaving a head and a hollow cutter bar within said head, comprising: achannel member of a length sufficient to extend along, and enclose saidhead; a brush supporting member contained within and extending throughout the length of said channel member, and be ing fixedly secured at itsone extremity to said channel member, the other extremity of said brushmember being free. for insertion in the hollow cutter bar to hold saidcap in place on said head and bristles projecting radially outwardfromsaid brush supporting member throughout its length.

8. The combination with an electric shaver having a hollow slottedcutting head, of a cap member shaped to enclose said head; and abristled brush secured to said cap member and extending into the hollowof said head.
